M4-CGM General Purpose Application Controller
Installation Guide
Application
The CGM09090 and CGM04060 General Purpose
Application MS/TP Controllers (CGMs) are equipment
controllers that run pre-engineered and user-
programmable applications, and provide the inputs and
outputs required to monitor and control a wide variety
of HVAC and other facility equipment. CGM controllers
operate on an RS-485 BACnet® MS/TP Bus as BACnet
Advanced Application Controllers (B-AACs) and integrate
into Johnson Controls® and third-party BACnet systems.
CGM equipment controllers include an integral real-
time clock, which enables the controllers to monitor and
control schedules, calendars, and trends, and operate for
extended periods as stand-alone controllers when offline
from the Metasys system network.
Communications Protocols
The CGM controllers can communicate using BACnet
MS/TP, N2, or wireless Zigbee®. By default, the CGM
controllers communicate using the BACnet MS/TP
protocol. The BACnet protocol is a standard for ANSI,
ASHRAE, and the International Standards Organization
(ISO) for building controls.
The CGM controllers can be used as functional
replacements for legacy N2 controllers. The N2-capable
MS/TP equipment controller models provide a cost-
effective upgrade and modernization path for customers
with existing N2 controllers. For installation and
commissioning support, and tips for efficient and safe
replacement, refer to the Modernization Guide for Legacy
N2 Controllers (LIT-12012005) and the controller-specific
documentation. For information about mapping N2
Objects in controllers with switchable communications
protocols, refer to the N2 Compatibility Options chapter of
the Controller Tool Help (LIT-12011147).
To configure CGM controllers to communicate using
the N2 communications protocol, see Configuring N2
communications.
The CGM controller can also be installed in a wireless
application using a ZFR183x Pro Wireless Field Bus Router.
To configure these controllers to communicate using
the wireless communications protocol, see Configuring
wireless communications.

Setting the device address
About this task:
Metasys equipment controllers are master devices on MS/
TP (FC or SA) buses. Before you operate controllers on a
bus, you must set a valid and unique device address for
each controller on the bus.
The following table describes the valid rotary switch
device addresses for communications bus applications.
Table 7: Switch device addresses
FC Bus Communication
Mode Valid Device Address Range
Wired MS/TP
communication
4-127
Note: Addresses 0-3 are
reserved and not for use on
equipment controllers.
Zigbee wireless
communication
4-127
Note: Addresses 0-3 are
reserved and not for use on
equipment controllers.
N2 communication
1-254
Note: Addresses 0 and 255 are
reserved and not for use on
equipment controllers.
The device address is a decimal address that is set
using three rotary switches located at the top of the
controller. The numbers are ordered from left to right,
most significant bit (MSB) to least significant bit (LSB)
when the controller is oriented as shown in Physical
features. In the following figure, the switches are set to 1
2 3, designating this controller's device address as 123.
Figure 10: Device address rotary switch block
The device address must match the device address
defined in the Controller Configuration Tool (CCT) under
Define Hardware > Network Settings.
To set the device addresses on CGM controllers, complete
the following steps:
1. Set a unique and sequential device address for
each of the devices connected on the FC or SA Bus,
starting with device address 4.
2. To ensure the best bus performance, set sequential
device addresses with no gaps in the device
address range (4, 5, 6, 7, 8, 9, and so on). The
devices do not need to be physically connected on
the bus in their numerical device address order.
3. Write each controller's device address on the white
label below the device address rotary switch block
on the controller's cover.
M4-CGM General Purpose Application Controller Installation Guide16

Refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for more information
about controller device addresses and how to
set them on MS/TP buses.
Removing a terminal block
About this task:
To remove a terminal block from the circuit board,
complete the following steps:
Note: You need a flat blade screwdriver to remove
the terminal block.
1. To prevent any possibility of damage from an
accidental short, remove power from the
controller.
2. Underneath the terminal block, in the small gap
between the bottom of the terminal block and
the circuit board, insert the flat blade of the
screwdriver.
Figure 11: Terminal block
3. To detach the left-hand side of the terminal block,
position the flat blade underneath the terminal
block to the left, and push down the screwdriver
handle. When you do this, you are using the
screwdriver as a lever to pry up the terminal block.
4. To detach the right-hand side of the terminal block,
position the flat blade underneath the terminal
block to the right, and push down the screwdriver
handle.
5. If necessary, repeat steps 3 and 4 until the terminal
block is removed.
Removing the controller cover
About this task:
Important: Electrostatic discharge can damage
controller components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the controller.
Important: Disconnect all power sources to the
controller before removing the cover and changing
the position of any jumper or the EOL switch on
the controller. Failure to disconnect power before
changing a jumper or EOL switch position can result
in damage to the controller and void any warranties.
The controller cover is held in place by four plastic
latches that extend from the base and snap into
slots on the inside of the housing cover.
To remove the controller cover, complete the
following steps:
1. Place your fingertips under the two cover lift tabs
(Physical features) on the sides of the housing
cover and gently pry the top of the cover away
from the base to release the cover from the two
upper latches.
2. Pivot the top of the cover further to release it from
the lower two latches.
3. Replace the cover by placing it squarely over the
base, and then gently and evenly push the cover
on to the latches until they snap into the latched
position.
Figure 12: CGM with cover removed showing EOL switch
and jumper positions (CGM09090 model shown)
Setting the End-of-Line (EOL) switch
About this task:
Each CGM controller has an EOL switch, which, when set
to ON (up), sets the controller as a terminating device on
the bus. See Figure 12 for the EOL switch location. The
default EOL switch position is OFF (down).
Figure 13: End-of-Line switch positions
To set the EOL switch on a controller, complete the
following steps:
1. Determine the physical location of the controller on
the FC bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note: For detailed information about EOL
termination rules and EOL switch settings on FC
buses, refer to the MS/TP Communications Bus
Technical Bulletin (LIT-12011034).
M4-CGM General Purpose Application Controller Installation Guide 17

3. If the controller is a terminating device on the FC
bus, set the EOL switch to ON. If the controller is
not a terminating device on the bus, set the EOL
switch to Off.
When a controller is connected to power with its
EOL switch set to ON, the amber EOL LED on the
controller cover is illuminated.
Setting the UI current loop jumpers
CAUTION
Risk of Electric Shock:
Disconnect supply power to the devices before
attempting to adjust the UI current loop jumpers.
Failure to disconnect the supply power may result in
electric shock.
ATTENTION
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation de l'controller avant tout
réglage du UI current loop jumpers. Le non-respect de
cette précaution risque de provoquer une décharge
électrique.
The UI current loop jumpers are on the circuit board
under the controller cover near the UI terminals (Figure
12). When a UI is defined (in the system software) as a
4-20 mA Analog Input, set the UI's current loop jumper to
the Enabled position (Figure 14).
Figure 14: UI Current Loop Jumper Positions
Setting the current loop jumper to the Enabled position,
connects an internal 100 ohm resistor across the UI
terminals, which maintains the 4-20 mA current loop
circuit even when power to the controller is interrupted or
off.
Important: Current Loop jumpers must be in the
Disabled (default) position for all UIs that are not set
up to operate as 4-20 mA analog inputs.
Important: A current loop jumper must be in the
Enabled position to maintain a closed 4-20 mA
current loop.
The following tables identify the current loop switches
associated with each UI on the CGM09090 and CGM04060
controllers.

Setting up a local display
CGM models do not have an integral display, but can
be connected to a DIS1710 Local Controller Display. For
detailed information about setting up and operating a
remotely connected DIS1710 display, refer to the DIS1710
Local Controller Display Technical Bulletin (LIT-12011270).
Input/Output Wiring Validation
The CGM controllers ship with a default state that can
assist in validating the wiring of the input and output
terminals prior to download of an application file. When
the controller is powered on in this state, the Fault LED
will flash in a pattern of two quick blinks and then a long
pause (see Table 10).
To make use of this feature, ensure the rotary switches
are set to the desired address and wire the input and
output terminals. Apply power to the CGM controller
and connect to the device with either a MAP Gateway
or MS-DIS1710-0 Local Display to view the points in the
controller. The CGM controller will report an Operational
status even though there is no true application loaded.
CCT will not be able to commission or upload the device
as a result until a true application is downloaded. The
application name displayed will be the address of the
controller followed by the model of the controller and
“Default State”.
For example, a CGM09090 controller whose rotary
switches are set to 8 would have the default state
application name of “8-CGM09090 Default State”.
The default state creates I/O points for all connections
on the input and output terminals. It assumes all
Universal Inputs (UIs) are Nickel temperature sensors. All
Configurable Outputs (COs) are treated as Binary Outputs
(BOs) with an initial value of 0. The default state also takes
input from a Network Sensor at address 199. If there is
M4-CGM General Purpose Application Controller Installation Guide18

no connected Network Sensor, the startup of this default
state will be delayed by 30 seconds as the controller
attempts to establish connection with the sensor.
Commissioning equipment controllers
You commission MS/TP equipment controllers with the
CCT software using either Mobile Access Portal (MAP)
Gateway , a ZFR wireless dongle, or in passthrough
mode when connected to a Network Engine. For detailed
information about commissioning equipment controllers,
refer to Controller Tool Help (LIT-12011147).
Troubleshooting equipment
controllers
Observe the Status LEDs on the front of the equipment
controller. Table 10 provides LED status indicator
information for troubleshooting the controller. To
troubleshoot an integral or local controller display, refer
to the DIS1710 Local Controller Display Technical Bulletin
(LIT-12011666).
